SAFETY PIN.

Application filed. Gctober 15, 1924, Serial No. 743,674. Renewed August27, 1925.

To 055 w/zcm 2t may concern;

Be it known that I, Lnoronn Hoorrnninnn, a citizen of Austria, residingat New York city, in the county of New York andState of New York, haveinvented certain new and useful Improvements in Safety Pins, of whichthe following is a specification.

This invention relates to safety pins, the invention having for anobject the provision of a novel and improved safety pin that can be moreeasily applied to and removed from the articles in connection with whichit is used. 1

A further objectof the invention is to provide a safety pin that can bereadily applied and removed without necessitating the use of two hands,and which will, when in use lie flat on the article to which it isapplied.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

Fig. 1 of the drawing is a face view of my improved safety pin.

Fig. 2 is a face view of the pin, but showing it as in actual use, theopposite face of the pin being shown in Fig. 2 to that shown in Flg. 1.

Fig. 3 is a face view of the pin showing the latter as being withdrawnfrom the article to which it has been applied.

Fig. 4 is a longitudinal sectional view taken on the line 4 l of Fig. 2.

Fig. 5 is a transverse sectional view-taken on the line 5-5 of Fig. 1.

Fig. 6 is a transverse sectional View taken on the line 6-6 of Fig. 3.

Fig. 7 is a transverse sectional view taken on the line 77 of Fig. 2.

Fig. 8 is a similar View to Fig. 1 but showing a modification.

Fig. 9 is a similar view to Fig. 1. but showing a further modification.

My improved safety pin is constructed entirely from a single length ofsuitable resilient wire that is pointed at one end to form the point ofthe pin. This Wire forms two main reaches 10 and 11 that extend parallelto one another, the reach being free at one end and pointed as at 10 toconstitute the point of the pin. At the other end of the reach 10 it isunited with the reach by a spring element formed by coiling the wire intwo turns, the wire being given one turn in the form of a circle 12while the other turn is projected to one side in the form of a flattenedloop 13, the purpose of this laterally projected loop being presentlyset forth.

The end of the reach 11 that is adjacent to the point of the pin is bentto form a relatively large loop 15 within the confines ofwhich the pointof the pin is located. The side of the loop 15 that is located nearer,or toward the parts 12, 13 preferably extends approximately in astraight line across the reach 10, as at 16 the loop 15 being completedby uniting the end of the wire to the reach 11, as at 17. Thistransverse member 16 preferably extends at a slightly oblique angle withrespect to the parts 10 and 11 as shown, and it may be joined to themember11 by. coiling its end around the latter. The loop 15 is formed,on the side thereof remote from the reach 11, with an inward projection19 of generally angular form whose apex is close to the pointed reach 10when the parts are in normal position. As clearly shown in Fig. 4 of thedrawing the loops 13 and Marc bent to lie in planes that are slightlyinclined to the plane in which the two main reaches 10 and 11 of the pinlie, the purpose of this arrangement being to assist in causing the pinto lie flat on the article to whichit is applied, as will be presentlypointed out.

In applying my improved pin the latter is placed in the position shownin Fig. 1 of the drawing upon the article to, which it is to be applied,the pointed end of the reach 10 being under the transverse member 16 ofthe loop 15. By pressing downward with the thumb, while the loop 13 isgrasped, the point 10 is caused to enter the article and the pin is thenmoved longitudinally a slight distance, the point being then permittedto emerge from the article. The pin is then twisted upon itself throughan angle of one hundred and eighty degrees, causing the transversemember 16 of the loop 15 to be engaged under the reach 16. It will benoted that the lateral projection of the loops 13 and 15 causes them toremain in this position to which the pin has been adjusted and in whichthe pin lies flat upon the article, while the angle or inclination abovereferred to of the loops 13 and 15 ensures the ends of the pin lying inclose contact with the article. It will be noted also that when the pinis applied as above set forth the transverse member 16 engages thearticle, indicated generally at A, in which the pin is placed it the pintends to slip out, and thereby prevents such slipping movement. When thepin is to be removed it is swung to its former position (that is to saythe position shown in Fig. 1) and then drawn backward. \Vhen thebackward movement of the pin starts the projection 19 presses againstthe article with which the pin is engaged and acts to lift thetransverse member 16 free of the latter so that the pin may be readilywithdrawn.

In Fig. 8 I have shown a modified construction in which the loop 15 isprojected further in a lateral direction and the in ward projection 19is omitted. In this construction the end transverse element of the loopis formed with an indentation to receive the point of the pin. The partsare otherwise as above described. This indentation 25 might be appliedto the construction shown in the other views if desired.

The pin shown in Fig. 9 is identical with that shown in Fig. 1 exceptthat the projection 19 is positioned somewhat differently.

I may, instead of simply inclining the loops at the ends of the pin givethe latter a general curvative from end toend.

Having thus described my invention What -I claim as new and desire toprotect by Letters Patent of the United States is as follows 1. A safetypin formed of a length of wire bent to form two parallel reaches, saidreaches being united at one end in a transversely projected coil, one ofthe reaches having its other end pointed, the other reach being formedat its other end to present a loop in which the said pointed endengages, the said loop and coil extending at a slight inclination to theplane of the said reaches.

2. A safety pin formed of a length of wire bent to form two parallelreaches, said reaches being united at one end in a transverselyprojected coil, one of the reaches having its other end pointed, theother reach being formed at its other end to pre sent a loop in whichthe said pointed end engages, the said loop presenting a transverseinner end member that projects across the first named reach.

3. A safety pin formed of a length of wire bent to form two parallelreaches, said reaches being united at one end in a transverselyprojected coil, one of the reaches having its other end pointed, theother reach being formed at its other end to present a loop in which thesaid pointed end engages, the said. loop presenting a transverse innerend member that projects across the first named reach, at a slightoblique angle.

4:. A safety pin formed of a length of wire bent to form two parallelreaches, said reaches being united at one end in a transverselyprojected coil, one of the reaches having its other end pointed, theother reach being formed at its other end to present a loop in which thesaid pointed end engages, the said loop presenting a transverse innerend member that projects across the first named reach, the said topbeing formed on one side with an inward projection extended toward thesaid first named reach.

5. A. safety pin formed of a length of wire bent to form two parallelreaches, said reaches being united at one end in a transverselyprojected'coil, one of the reaches having its other end pointed, theother reach being formed at its other end to present a loop in which thesaid pointed end engages, the said loop presenting a transverse innerend member that projects across the first named reach, the said topbeing formed on one side with an inward projection extended toward thesaid first named reach, said projection being of angular form and havingits apex adjacent the said first named reach.

In testimony whereof I have 'ar'fixed my signature.
